SažetakSvrha: Željelo se in vitro istražiti učinak ispiranja aktiviranog različitim erbijskim laserima na čvrstoću vezivanja individualnog kolčića ojačanog vlaknima na dentin korijenskog kanala. Materijali i metode: Dvadeset i sedam jednokorijenskih zuba endodontski su tretirani i poslije preparacije za postavljanje intrakanalnog kolčića podijeljeni u tri skupine (n = 9 po skupini), ovisno o vrsti predtretmana korijenskog dentina: 1. skupina -konvencionalno ispiranje fiziološkom otopinom (kontrolna skupina); 2. skupina -ispiranje fiziološkom otopinom i aktivacija PIPS nastavkom lasera Er:YAG; 3. skupina -ispiranje i aktivacija RFT2 nastavkom lasera Er,Cr:YSGG. Dva uzorka iz svake skupine upotrijebljena su za SEM analizu. U preostale je (n = 7 po skupini) cementiran individualni kolčić ojačan vlaknima everStick POST -korišten je samoadhezivni cement G-CEM LinkAce. Nakon cementiranja uzorci su prerezani okomito na uzdužnu os na nove jedan milimetar debele uzorke koji su podvrgnuti push-out testiranju (0,5 mm/min.). Rezultati su zabilježeni u MPa-u, a logaritmirani i statistički analizirani su ANOVA testom na razini značajnosti od 5 posto. Rezultati: U kontrolnoj skupini zaostatni sloj bio je još prisutan, u skupni Er:YAG bio je uklonjen, a u skupini Er,Cr:YSGG bio je djelomično uklonjen. U skupini Er,Cr:YSGG postignute su najviše vrijednosti čvrstoće vezivanja, slijedila je kontrolna skupina i tek tada skupina Er:YAG. Ipak, među vrijednostima čvrstoće vezivanja spomenutih skupina nije pronađena statistički značajna razlika (p = 0,564). Zaključak: Ispiranje aktivirano nastavcima erbijskih lasera PIPS i RFT2 nije utjecalo na čvrstoću vezivanja individualnih kolčića ojačanih vlaknima na dentin korijenskog kanala. Zaprimljen

“…According to Baran et al, the incidence of post fracture in clinical settings is associated with the mechanical properties of the post itself ( 14 ). In general, there are several factors that contribute to the mechanical strength of a fiber post and they include the individual properties of the fiber and matrix, polymerization shrinkage of the resin, intracanal irrigation systems, bonding between the fibers and matrix resin, the direction of the fibers as well as the volume fraction and proportion of fibers that were being impregnated into the resin matrix ( 11 , 15 , 16 ). The retention of fiber posts is depended on bond strength between the resin luting agent and the post and also the bond strength between the dentin and the resin luting agent ( 17 ).…”

Objective Endodontically treated teeth may require posts for retaining the core and replacing the coronal structures that have been lost. The objective of this study was to evaluate and compare the push-out bond strength between different types of post cemented with different types of luting cement at different types of root level. Materials and Methods In this in-vitro study, a total of 48 single-rooted permanent human teeth were decoronated, and the roots were treated endodontically. Following post space preparation, the sample was divided into four groups (n= 12 each) based on the types of post and cement. Two different types of post [GC everStick ® POST (ES) and Parapost ® Fiber Lux TM (PF)], and two different types of cement [G-CEM TM (G), and RelyX TM Unicem (R)] were used according to the manufacturer’s instructions. All roots were sectioned at the coronal and middle thirds with a thickness of 3±0.1mm. The Push-out bond strength (PBS) test was performed using a universal testing machine at a cross-head speed of 0.5mm/ min. The bond strength values were recorded, and the data were analyzed using the SPSS program. Apart from descriptive statistics, three-way ANOVA was used for the interaction of the independent variables (post, cement, and root level). For differences between the groups, the Mann-Whitney U test was used. A P-value of less than 0.05 was considered significant for all analyses. Results Push-out bond strength of samples at the middle level (11.38±10.31 MPa), with PF posts (11.18±9.98 MPa), and of those luted with RelyX TM Unicem cement (13.26±8.73 MPa) was higher than that of their counterparts. The PBS means of RelyX TM Unicem cement at both root levels were much higher than PBS means of G-CEM TM cement. Three-way ANOVA test revealed a significant effect for each variable with a higher effect of cement (Sum of Squares= 1310.690; P< 0.001). No significant difference (P= 0.153) was found between the coronal and middle parts and between ES and PF posts (P= 0.058). However, a highly significant difference (P< 0.001) was found between RelyX TM Unicem and G-CEM TM cements. Conclusion The type of cement had a significant effect on push-out bond strength with RelyX TM Unicem which had higher values than G-CEM TM . However, the type of post and root level had no significant effect on PBS, although Parapost® Fiber Lux TM and middle root level had higher values than their counterparts.

“…Uno de los principales problemas que se han evidenciado en la utilización de pernos intrarradiculares es la descementación de los mismos (5), falla que puede deberse a varios factores como: la falta de eliminación del barrillo dentinario originado durante la preparación del conducto radicular (6,7), las soluciones irrigantes empleadas que pueden interferir en los procesos de adhesión posteriores (8), así como también por la falta de tratamiento del perno previa a la cementación (2,9).…”

“…Otro factor importante a considerar es la característica de la dentina en las diferentes zonas del conducto radicular, debido a la disposición y cantidad variada de túbulos dentinarios en cada una de estas porciones. Por tal motivo, Arısu et al en el 2013, Kul et al 2016, Crispim da Silveira et al 2014, entre otros autores, realizan comparaciones en los diferentes segmentos con empleando varias soluciones irrigadoras en las que se puede evidenciar comportamiento variado en cada una de ellas (5,7,8,10,11,12) Es importante tener en cuenta que la matriz del perno de fibra debe mantenerse después de su tratamiento ya sea este químico o mecánico, es decir, dicho tratamiento debe mejorar la adhesión sin alterar la estructura del mismo. Esta característica se la puede observar bajo microscopía electrónica después del desprendimiento del mismo del conducto radicular como lo indican Monticelli et al, Mazzitelli et al, Talebian et al (13,14,15,16) Por ello el propósito de esta revisión consiste en identificar tanto el tratamiento de superficie de pernos de fibra como el irrigante radicular idóneos para conseguir una cementación adecuada y, asimismo, conocer cuál es el tratamiento de superficie que produce menos desintegración de las fibras del perno de fibra.…”

Objetivo: identificar tanto el tratamiento de superficie de pernos de fibra como el irrigante radicular idóneos para conseguir una cementación adecuada; así como conocer cuál es el tratamiento de superficie que produce menos desintegración de las fibras del perno de fibra. Materiales y métodos: se incluyeron 47 artículos publicados en inglés, durante los últimos 20 años, teniendo en cuenta que los mismos se obtuvieron hasta octubre del 2018. Conclusiones: previa la cementación de pernos sean estos de fibra o de cuarzo es indispensable realizar tratamiento de superficie para así mejorar la adhesión, estos pueden ser químicos o físicos, los que ofrecen mejor resultado sin alterar de manera significativa la estructura del mismo es el enarenado con partículas de diamante sintéticas de 1-3 µm seguido de silanización y dentro de los químicos H2O2 al 10% por 1 min seguido de silano. Para obtener mejores resultados se debe accionar el silano a una temperatura de 80°C. En cuanto a protocolos de irrigación depende del sistema de cementación que se vaya a emplear EDTA 18% + Hipoclorito de sodio al 5,25% o EDTA 18% + clorhexidina al 2% cuando se va emplear un cemento autoadhesivo y NaOCl al 11% cuando se utilice el acondicionamiento ácido de lavado y secado.Palabras clave: perno; endodóntico; preparación del diente; irrigantes del conducto radicular; EDTA.ABSTRACT Introduction: nowadays the aim is to keep the dental organ in function as long as possible, in many cases the endodontic treatment is used to preserve the dental pieces; and the use of fiber post when the coronary remnant is not adequate to receive a crown prosthesis, allowing us in these cases rebuilt the thoot for the subsequent placement of the final restoration. Objective: to identify wich is the better surface treatment of fiber post and the root irrigator for adequate cementation; as well as know, which is the surface treatment that produces less fibers' disintegration of the fiber post. Materials and methods: it were included 47 articles published in English, during the last 20 years, considering tha...
